Universal H-Series Low NOx Heaters
For In-Ground Pools and Spas - Electronic Ignition Dual Thermostat
Now With Cupro Nickel Heat Exchanger!
NEW Hayward Universal H-Series Low NOx heater combines industry-leading hydraulic performance; environmentally responsible low NOx emissions and a standard cupro nickel heat exchanger with a low profile appearance, lighter weight design, independent left or right side electric, water and gas connections plus 2" x 2 1/2" CPVC union connections to provide the ultimate installation flexibility for new or existing equipment pads.
It also includes a forced draft system that constantly moves air through the combustion chamber at a precise flow rate. As a result, all outside weather variables that can affect the heating performance, such as wind conditions, are eliminated - without having to install a high-wind stack.
NOTE: The Hayward Universal H-Series heaters meet the NOx Emission standards set by the California South Coast Quality Air Management Commission for 2001 and the Texas Natural Resource Conservation Commission Code.
I have a Hayward heater, model # H150FDN. The face plate fell off and I believe the small mother board right behind the plate is fried.
i started my heater today ran fine then i shut it down an won't restart the code lo comes up on the screen
Hi, Jeffrey. The LO error code references the Limit string open error. You will need to check the Limit Switch - FDXLHLI1930 or the Integrated Control Board - FDXLICB1930 to find out which part is bad and will need to be replaced. Also, it could be a bad Water Pressure Switch - FDXLWPS1930, confirm that the unit is getting at least 30 GPM.
Is this a new Hayward 150000 BTU water heater model. I notice that there is a cover over the temperature gauges. But on the other Hayward 150000 BTU heaters, the temperature gauges does not have a plastic cover and they are different then other heaters i described. Which is the most up to date? The Hayward heater with the plastic cover or the heater without? I especially love the Hayward heaters with the cover. It protect against the rain and snow.
Hi. This unit is the most recent H Series heater model by Hayward.
How long would it take for this heater to raise the temperature of a standard size in-ground jacuzzi about 15 degrees?
Hi, Nicolette. The answer to your question will be based on the actual surface area of the spa. You can use the Hayward Heater BTU Selection Guide to calculate the temperature increase of your spa after calculating the surface area.
How can I tell what year the model was manufactured?
There should be a mfg. date on the label of the heater, or if you find a serial # you can contact Hayward at www.haywardpool.com and they will be able to tell you the year of mfg.
Does this heater require its own electric hook up or can I feed it from my existing 120V pump? Also, is it equipped with a fireman switch? Thank you
Hi, Dimi. This unit requires an electrical hook, the source of the supply doesn't matter. A fireman switch is not included with the unit.
I plan to build my own pool and the architect needs the pump and heater information. The outside, inground pool is going to be 10' x 20' with an average depth of 5'. I will be using 2-1/2" PVC pipe and I calculated 20' feet of head. I think the Hayward SP2600X5 pump will work. Can you please confirm my calculations and let me know what size water heater I will need. I want to be able to swim in water that is 70 degrees Fahrenheit in the winter when the temps at times fall to the mid 30's.
Good afternoon Francoise, I would recommend at least the 200,000 BTU model, part number H200FDN, though if you are going to have a saltwater pool I would recommend the heater with a cupro-nickel heat exchanger to prevent corrosion and leaks to your heat exchanger, part number TR250NA. As for the SP2600X5, that will work just fine just as long as you do not have any water features. If that is the case then I will need to know all the features so I can calculate the correct horsepower for your pump.
Can I have my outside pool heater running during in a heavy rain and wind storm with possible thunder and lightening?
Hi, Dona. This unit can be run under those weather conditions as long as the proper safeguards are in place to protect the unit from flooding and being strike by lighting. You can review the Hayward Universal H-Series Owner's Manual for more info.

Do you have a manual bypass valve kit for a H150FDN pool heater?
Hi Bill, You can build your own external manual bypass using a 3-Way Valve and Tee. Or if you're looking to replace the Bypass Cartridge Kit-FDXLBPK1930, that part is available.
Will this heater work with a 16 x 32 above ground pool?
Scott, For a 16' x 32' pool, I would recommend at least 200-250k btu. The lower the btu, the longer it will take to heat the pool.
Will the Hayward H1001D1 100,000 BTU unit work at an elevation of 3500 ft??
Yes this unit will work up to an elevation rating up to 7,700 feet.

The heater that would reach the heating requirements would be the H400FDN.
Can above ground pool heaters be used on inground pools?
Hello, As long as the heater is sized correctly for the pool size, you can use an above ground heater for an in-ground pool. Please double check the gas line requirements to ensure that you will be able to have the heater installed with no issues.
i have a 16 x 32, what size heater do i need?
Hi Troy, The Hayward Pool Heater Universal H-Series Low Nox 200K BTU NG will be a better size for your pool.
I want to install the Hayward Lownox heater on my pool but I live in the mountains at 3,000 foot elevation; do I need to buy a special high elevation heater?
Hello George, The Hayward Universal Low Nox are self adjusting up to 10,000 feet of elevation. Any installation above 2,000 feet will require a special restriction plate to be installed. Luckily, that plate comes standard with every heater so no need to purchase it separately.
Can I hook up an inground heater to an above ground pool?
Hello Chris - The inground heaters can be used on above ground pools.
Where can my heater be installed?
There are specific venting requirements and clearance distances that must be met to ensure proper operation. Consult the owner’s manual for exact specifications for your model of heater.NOTE: Gas fired heaters should be diagnosed and repaired by trained personnel.
Is it possible to convert this heater from natural gas to propane?
Is a vent required for typical outside installation for the Hayward 150k Ng Lo Nox heater?
For the Hayward Lo Nox heater, you would not need to purchase an additional vent if you are using it outside. If you are installing the heater outside, we recommend you purchasing a heater cover. This will protect your heater from debris, rain, snow, heat- or pretty much anything that could get caught in your heater. The Weather-Out Pool Heater Cover can be viewed on our website.
What is the elevation rating for the Hayward H-Series Low Nox Heaters
Per Hayward, the Hayward H-Series Low Nox Heaters have an elevation rating up to 7,700'
What is the difference between an Electronic and Millivolt ignition?
The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.
Will a gas heater operate at the low speed of a dual speed motor?
Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.
How do you know if a pool heater is a propane heater or a natural gas heater?
Typically in the product name we use the abbreviation of "LP" for propane or "NG" for natural gas. Click here for a full listing of our >Pool Heaters.
